Unionville Commercial Core Pattern Book Village Design and - PowerPoint PPT Presentation

Unionville Commercial Core Pattern Book Village Design and Architectural Guidelines Presentation to Development Services Committee April 16, 2018 1

Purpose • To provide an overview of the Unionville Commercial Core Pattern Book • To recommend that Council approve the document for use in the review and evaluation of commercial and residential intensification development applications in the commercial core area of historic Unionville 2

Area Context Carlton Road Fred Varley Dr. Main Street Station Ln 3

Background • Main Street Unionville Community Vision Plan – Major, comprehensive 2 year study (2013-2014) – From Hwy 7 to Toogood Pond – a number of focus areas – To address specific issues impacting the ongoing success and stability of historic Unionville – Examine new opportunities and strategies to support/enhance • Key Opportunity – Commercial Core Area – Better use of the large amount of underutilized lands – Promotion of residential uses behind existing buildings to help bolster year-round livability and use of the street 4

Background • The proportion or massing of these new buildings and their style will be compatible with the heritage character of the area (1½-2 storeys) and are depicted to be 3 to 3 ½ storeys in height, primarily gable- roofed, residential building forms. 6

Background • Vision Plan recommended: – “the City work to put in place the regulatory documents that would be required…and commission a Pa Pattern ttern Book k to guide the architecture” • Pattern Book would help direct the design of infill development: – A historically inspired guidebook for the design of new multi-storey buildings that reflect and respond to their context. • The Heritage District Plan did not provide guidance on this form of new development (greater height, larger massing) 7

Background • Council adopted a series of recommendations (January 2015) – That the Vision Plan “be endorsed in principle as a guideline for a future secondary plan for the area and that the City and other affected parties/stakeholders be guided by the general direction of the Vision Plan when initiating or reviewing proposed changes in both the public and private realms of the Unionville Heritage Conservation District”. – That staff be authorized to undertake “the preparation of a Pattern Book to help guide the overall design review of new multi-storey development”. 8

Pattern Book Study • City retained Torti Gallas and Partners with Michael Morrissey to undertake the Pattern Book study • They were the prime consultants on the Vision Plan study • Objective: to prepare a concise and well illustrated document providing architectural and urban design guidance for new infill development in keeping with the adopted Vision Plan 9

Pattern Book Study • Objective: Form, massing and architecture of new infill to be compatible with and not diminish the existing character and cultural heritage resources. • There were concerns during the Vision Study that the proposed scale and height of the illustrated new development could potentially threaten, diminish or overshadow the existing heritage resources and affect the village-like character of historic Unionville. 10

Composition of the Pattern Book Consists of three components: Introduction and Policy/Regulatory Framework Village Design Guidelines Architectural Guidelines 11

Part 1 – Overview and Policy/Regulatory • Provides a brief overview of what is to be protected – “angled main street, picturesque assemblage of charming village-scale buildings, delicately interwoven private and public space” – “an authentic nineteenth century Ontario village” • Provides a basic guide to property owners, architects, builders and City staff to understand the design principles that will create compatible development • Notes the need for predictable outcomes to provide security for the public. • Intended to provide a degree of certainty and clarity, but as guidelines they are afforded some flexibility in application. 12

Part 1 – Overview and Policy/Regulatory • To work with other statutory and non-statutory plans, policies and regulations – Main Street Unionville Community Vision Plan – Unionville Heritage Conservation District Plan – Markham Official Plan 2014 – Toronto and Region Conservation Authority Provincial Regulations 13

Core Area Detail Plans - Example 23

General Development Standards • Building Massing and Design Treatment • What is encouraged : – Residential in character, scale and proportions/ complementary rooflines – Primary building mass with attached wings – Well articulated buildings – Consistent and cohesive design elements/ limited types of window, doors – Building assembles made up of smaller buildings with own entrance – High quality materials, durable 24

General Development Standards • Building Massing and Design Treatment • What is discouraged : – Corridor buildings with single entrance/ single cores – Formal massing with long unbroken façade lengths – Overly repetitive motifs, unarticulated blank walls – Vertically ganged windows, extensive glazing – Overly complicated massing without a hierarchy of forms – Tall building massing without stepping down – Excessive use of projecting balconies or highly visible terraces 25

General Development Standards • Massing Guidelines • Height – 3 storeys to the roof eave – Occupied roof above the 3 rd floor (3 ½ storeys) • Building Size – Maximum footprint to achieve moderate massing – Encourage linkages • Façade Treatment – Articulation of the facade 26

Part 3 – Architectural Guidelines 27

Architectural Guidelines Appropriate Styles for Larger Scale Building: • Vernacular / Gothic Revival • Georgian / Regency • Italianate • Edwardian Classical 28

Georgian Regency Example • Brief overview of the style • Typical features are listed • Examples are provided of building type and sample details/materials • Illustrative massing and composition diagram 29

Staff Recommendations • That Council approve the “Unionville Commercial Core Pattern Book- Village Design & Architectural Guidelines” for use in the evaluation of current and new residential and mixed-use intensification development applications in the commercial core area of historic Unionville”. • That Council direct staff to monitor the effectiveness of the Pattern Book for period of at least two years and determine if any further revisions to the document or related policies and implementation tools are warranted for Council consideration. 36
